Cook error in 5.7.1

Cesium for Unreal
1

Anyone seen this before? The error triggers when trying to package a project in UE 5.7.1. This project was just upgraded from 5.4.4 where it had no troubles cooking.

I should note, this is using the Cesium plugin released today (Jan 6).

Hi @flav,

Sorry you’re having trouble. Can you please check if the Cesium for Unreal Samples project packages successfully? That may help narrow down where the problem lies.

Hey @Kevin_Ring ,

The sample project packages fine, but it obviously doesn’t have the same actors in the world, so it doesn’t help much. I’m trying to narrow down what specific actor/asset might be causing it. But let’s say I find the 3dtile that’s causing the cook error, what would be the next step to make progress?

@Kevin_Ring I managed to get a repro in the cesium sample project.

  1. create a project form the Cesium Sample
  2. add a new blank tileset
  3. set source to ellipsoid
  4. add the imagery (id 2) to it (unsure if this is needed)
  5. package Development for Windows
